[0002] In recent years, with the maturity and development of various technologies, electric vehicles have attracted more and more attention and favor from consumers due to advantages such as environmental protection, subsidies, tax reduction, and license plate. However, electric vehicles are plagued by battery endurance problems. In order to solve this problem, various mobile charging vehicles or vehicle-mounted charging stations using clean fuel have been researched and implemented. Among them, methanol is widely used in generator sets as fuel due to its small pollution, low price, and renewable nature.

[0003] For example, the Chinese utility model patent with the authorization publication number CN219927481U discloses a silent container-type methanol self-generating charging equipment, which includes a box-type container. The box-type container is divided into a fuel chamber, an exhaust chamber, a machine cabin chamber, and a charging equipment chamber along the length direction of the box body. The fuel chamber is divided into multiple cavities by a partition. Each cavity is provided with at least one methanol fuel tank for loading methanol fuel. The machine cabin chamber is installed with a methanol generator set. The outlet of the methanol fuel tank is communicated with the fuel inlet of the methanol generator set. The exhaust chamber is installed with a smoke silencer. The smoke outlet of the methanol generator set is communicated with the inlet of the smoke silencer. The outlet of the smoke silencer is communicated to the outside of the box-type container for discharging the flue gas generated by the methanol generator set. At the same time, the air outlet of the heat dissipation assembly on the methanol generator set is also communicated to the exhaust chamber. An exhaust silencing window is arranged on the exhaust chamber for exhausting the heat in the box-type container to the external environment, thereby dissipating heat inside the box-type container. The charging equipment chamber is provided with an energy storage battery pack and an integrated charging system. The integrated charging system is used to convert the power of the methanol generator set and the power of the energy storage battery pack and supply power to the power distribution equipment. In addition, a fuel maintenance door is installed on one end of the box-type container to facilitate the maintenance and repair of the methanol fuel tank. A ventilation louver is also arranged on the fuel maintenance door to reduce the temperature of the fuel chamber and prevent the methanol content in the air inside the fuel chamber from being too high.

[0014] By using the above technical scheme, the methanol fuel tank located in the middle is used for filling methanol and supplying methanol fuel to the other two methanol fuel tanks, and the other two methanol fuel tanks are used for delivering methanol to the methanol generator set, so only the methanol fuel tank located in the middle needs to be frequently transported, and only the connection with the other two methanol fuel tanks needs to be frequently disconnected or connected, compared with the case that each methanol fuel tank needs to be filled after being used up, it is not only more convenient and fast, but also reduces the number of pipelines that need to be frequently disconnected, thereby reducing the possibility of leakage of the methanol fuel tank.

[0015] In addition, three methanol fuel tanks are arranged in three chambers respectively, and three ventilation openings are arranged in the three chambers, and three liquid nitrogen tanks are arranged, so that when the methanol fuel tank in one chamber leaks, nitrogen can be filled in the chamber to cool the chamber, and the working state of the methanol fuel tanks in other chambers is not affected, and the three chambers are relatively independent, so that the operation efficiency of the equipment is improved.

[0057] The implementation principle of the methanol generator protection device with smoke removal and heat dissipation provided in the embodiment is as follows: the supplementary tank 31 located in the middle is used for filling methanol and supplying methanol fuel to the other two feeding tanks 32, so only the supplementary tank 31 needs to be frequently transported, and only the connection position of the supplementary tank 31 and the feeding tank 32 needs to be frequently disconnected and connected, compared with the case that each tank needs to be filled after being used up, the method is not only convenient and fast, but also reduces the number of pipelines that need to be frequently disconnected and connected, and reduces the possibility of leakage of the methanol fuel tank 3.

[0058] When the filling of the supplementary tank 31 is completed, it is necessary to transfer it to the middle chamber 22, along the partition 21 to push the transfer support 4, while slowly retracting the telescopic cylinder 433, so that the bottom of the transfer support 4 is in abutment with the bottom surface of the chamber 22, and as the transfer support 4 continues to be pushed, the two folding wheels 43 in front of the advancing direction slowly enter the folding groove 44, at this time, continue to push the transfer support 4, the two folding wheels 43 behind the advancing direction also slowly enter the folding groove 44, and finally the transfer support 4 is completely pushed into the chamber 22, completing the fixing of the supplementary tank 31.

[0059] The installation of the quick connector assembly 5 is completed at the same time as the process of the supplementary tank 31 entering the methanol fuel chamber 2, when the transfer support 4 of the supplementary tank 31 is pushed, the two ends of the shunt pipe 52 enter the two rotating pipes 532 respectively, at this time the slider 537 on the shunt pipe 52 enters the corresponding spiral groove 535, as the slider 537 slides, the rotating pipe 532 is driven to rotate, the rotating pipe 532 drives the connecting ring 538 to rotate, when the transfer support 4 is pushed to the abutment of the connecting ring 538 and the telescopic pipe 540, at this time continue to push the shunt pipe 52, the spring 543 exerts pressure on the sealing ring 542, so that it is in abutment with the connecting ring 538, the telescopic pipe 540 is compressed, the shunt pipe 52 can continue to slide, driving the rotating pipe 532 to continue to rotate, at this time the clamping arc rod 5391 on the connecting ring 538 rotates into the corresponding clamping buckle 5392 on the telescopic pipe 540, thereby locking the connecting ring 538 and the telescopic pipe 540. At the same time, due to the action of the spring 543, the sealing ring 542 is in abutment with the connecting ring 538, completing the sealing of the quick connector 53. With the process of resetting the supplementary tank 31, the connection of the supplementary tank 31 and the two feeding tanks 32 is completed, which is convenient and efficient, reduces the workload of the staff, and improves the work efficiency.

[0060] After the installation of the supplementary tank 31 is completed, open the valve 274 on the fixed pipe 531 of the two feeding tanks 32, and close the fuel maintenance door 11.

[0061] The methanol concentration sensor 61 monitors the methanol concentration in the chamber 22. When a methanol leak occurs, the methanol concentration sensor 61 detects that the methanol concentration in the chamber 22 is too high, and the control drive motor 247 is started to drive the ventilation plate 241 to rotate to close the air vent 23, preventing the leakage of methanol from leaking out, avoiding poisoning of the user, and at the same time sealing the chamber 22 space, facilitating spraying liquid nitrogen cooling. The electric valve 66 of the liquid nitrogen tank 62 is opened, and the liquid nitrogen in the liquid nitrogen tank 62 is sprayed out from the nozzle 65 through the spray pipe 64, on the one hand to cool the chamber 22, and on the other hand to fill the chamber 22 with inert gas to prevent the leaked methanol from burning, thereby protecting the equipment and the user. At the same time, the chamber 22 status light 67 of the chamber 22 where the methanol leak occurs turns red to serve as a warning and to facilitate maintenance personnel to find the methanol fuel tank 3 that needs to be repaired.

[0062] When it is necessary to fill the replenishment tank 31 with methanol, the valves 274 on the two feeder tank 32 fixed pipes 531 are closed, the connecting ring 538 is rotated, the clamping arc rod 5391 on the connecting ring 538 is separated from the clamping buckle 5392 on the telescopic pipe 540, the transfer support 4 of the replenishment tank 31 is pulled outwards, the slider 537 on the shunt pipe 52 slides away from the feeder tank 32 at this time, the rotating pipe 532 also rotates in the opposite direction, the shunt pipe 52 gradually separates from the rotating pipe 532, and the quick connector 53 is disconnected, thereby completing the separation of the replenishment tank 31 and the feeder tank 32. During the process of pulling out the transfer support 4 of the replenishment tank 31, the four folding wheels 43 gradually extend from the folding grooves 44, thereby supporting the transfer support 4 to facilitate the transfer and fixation of the replenishment tank 31 by the staff.
